Plan B One-Step is a pill that reduces the risk of pregnancy by 89% if you use it within 72 hours (three days) of the unprotected sex. According to the manufacturer, seven out of eight of the women who would have gotten pregnant will prevent pregnancy by taking Plan B. The sooner you use Plan B after the unprotected sex, the more effective it is. Plan B can be used up to five days after unprotected sex, but it is less effective.
